[0002] Connectors typically consist of a housing, terminals housed within the housing, and a cable that connects to the terminals and extends out of the housing. The cable connects to electrical equipment. However, when the cable is made of rigid materials such as aluminum busbars, the cable may need to be bent to eliminate positional errors due to installation errors of the connector and other related components. This can affect the proper fit between the cable and the housing, potentially causing structural damage or seal failure. Utility Model Content

[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0038] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] like Figure 1-4As shown, an embodiment of this utility model provides a high-tolerance connector, which includes a housing 1, a first conductor 2, a second conductor 4, and a fixing structure. The first conductor 2 is at least partially disposed inside the housing 1, and one end of the first conductor 2 is connected to the second conductor 4 along a predetermined direction A. The one end of the first conductor 2 can be offset relative to the second conductor 4 in the predetermined direction A, or it can be offset relative to the predetermined direction A in all directions. Alternatively, it can be described that the second conductor 4 can be offset relative to one end of the first conductor 2 in the predetermined direction A, or it can be offset relative to the predetermined direction A in all directions. This offset in all directions should be understood as a linear relative displacement between the first conductor 2 and the second conductor 4, or a rotational relative displacement around a certain axis, or a composite relative displacement formed by a combination of linear relative displacement and rotational relative displacement. The fixing structure is covered on the outer periphery of the conductive connection between the first conductor 2 and the second conductor 4, and the two ends of the fixing structure are respectively connected to the housing 1 and the second conductor 4.

[0042] In this scheme, one end of the first conductor 2 can be offset relative to the second conductor 4 in a predetermined direction and offset in all directions relative to the predetermined direction. Therefore, when the first conductor 2 and the second conductor 4 cannot be connected in the predetermined correct position, the second conductor 4 can adjust its position according to the actual position, thereby successfully establishing a connection with the first conductor 2, tolerating and eliminating positional errors, and avoiding the undesirable phenomenon of the second conductor 4 being forced to bend. In addition, the fixing structure can fix the first conductor 2 and the second conductor 4 after the connection relationship is established, so as to stabilize the connection between the first conductor 2 and the second conductor 4.

[0043] Obviously, in other embodiments, one end of the first conductor may be offset relative to the second conductor only in a predetermined direction, or offset only in all directions relative to the predetermined direction.

[0044] Furthermore, to facilitate the connection between the first conductor 2 and the second conductor 4, such as... Figure 3 , 4 As shown, in this embodiment, one end of the first conductor 2 extends out of the housing 1 and is electrically connected to the second conductor 4, while the other end is located inside the housing 1 and connected to a terminal 11. That is, the first conductor 2 is only partially disposed inside the housing 1. More specifically, the first conductor 2 can be integrated with the housing 1 by an embedded injection molding process. In addition, the terminal 11 includes a body and a fixing screw, which is a conventional structure.

[0045] Obviously, in other embodiments, the first conductor may also be entirely located inside the housing, but the end of the housing corresponding to the second conductor needs to have a cavity to accommodate the end of the second conductor so that the first conductor and the second conductor can be smoothly connected. This solution is easily understood and obtained by those skilled in the art, so it will not be described in detail here.

[0046] Furthermore, considering ease of assembly and disassembly and connection stability, one end of the first conductor 2 is connected to the second conductor 4 via a bolt 3 structure.

[0047] Specifically, such as Figure 3 , 4 As shown, in this embodiment, a nut 31 is provided at one end of the first conductor 2, and a fixing hole 42 is provided on the second conductor 4. The nut 31 can be fixed to one end of the first conductor 2 by riveting. A bolt 3 corresponding to the nut 31 is inserted into the fixing hole 42. The bolt 3 and the nut 31 constitute the above-mentioned bolt 3 structure.

[0048] Furthermore, such as Figure 3 , 4 As shown, in this embodiment, the fixing hole 42 is an elongated oval hole structure extending along a predetermined direction A. The width of the elongated oval hole structure is the same as the diameter of the threaded portion of the bolt 3. Thus, in this embodiment, the second conductor 4 can be offset relative to one end of the first conductor 2 along the predetermined direction A, or it can rotate around the axis of the bolt 3 relative to the predetermined direction A, or it can have both offsets.

[0049] Obviously, in other embodiments, the width of the elongated hole structure can also be greater than the diameter of the threaded portion of the bolt, so that the second conductor can also be offset linearly in all directions relative to the predetermined direction; the fixing hole can also be a circular hole structure, and the diameter of the circular hole structure can be greater than or equal to the diameter of the threaded portion of the bolt; the fixing hole can also be an irregular hole structure such as an L-shape or a Z-shape.

[0050] Furthermore, in order to make this solution applicable to metal materials with poor contact conductivity, and to improve the conductive connection performance between the first conductor and the second conductor, conductive transition structures are provided at the opposite positions of one end of the first conductor 2 and the second conductor 4, namely the first conductive transition structure 21 and the second conductive transition structure 43. After one end of the first conductor 2 and the second conductor 4 overlap, they contact and conduct electricity through the conductive transition structures. The conductive transition structures can be made of materials with excellent contact conductivity, such as copper or silver.

[0051] like Figure 4 As shown, in this embodiment, in order to meet the cost reduction requirements, both the first conductor 2 and the second conductor 4 are made of aluminum. One end of the first conductor 2 and the second conductor 4 are both flat structures. The conductive transition structure is made of copper and is respectively set on the plane opposite to one end of the first conductor 2 and the second conductor 4.

[0052] Furthermore, to prevent the edges from being too sharp, at least one of the ends of the first conductor 2 and the second conductor 4 facing the first conductor 2 has an arc-shaped structure, such as... Figure 3 , 4 As shown, in this embodiment, the end of the second conductor 4 facing the first conductor 2 has an arc-shaped structure.

[0053] In this embodiment, considering cost and processing technology, the fixed structure is heat shrink tubing 5.

[0054] Considering insulation and sealing factors, an insulating layer 41 is provided on the outer periphery of the second conductor 4, one end of the heat shrink tube 5 is connected to the insulating layer 41 of the second conductor 4, and the heat shrink tube 5 is provided with a hot melt adhesive layer on the inner wall at least at both ends.

[0055] In other embodiments, the fixing structure may also be formed by solidifying an insulating coating of a certain thickness applied to the outside of the first conductor and the second conductor.

[0056] During assembly, the heat shrink tubing 5 can be pre-attached to the second conductor 4. After fixing the second conductor 4 to a position such as the vehicle body, it can be connected to the electrical equipment. Then, the housing 1, the first conductor 2, and the terminal 11 can be assembled with the mating connector. At this time, the second conductor 4 can be aligned with the first conductor 2, and the bolt 3 can be passed through the fixing hole 42 and connected to the nut 31. Then, the heat shrink tubing 5 can be moved to the connection point for heat shrinking until both ends of the heat shrink tubing 5 are fixedly connected to the insulation layer 41 of the housing 1 and the second conductor 4, respectively. This completes the assembly of the high tolerance connector. Based on the tolerance performance of this high tolerance connector, the first conductor 2 and the second conductor 4 can be connected smoothly without forcing the second conductor 4 to bend.

[0057] Figure 5-7 Three other representative assembled states of this high-tolerance connector are shown (all with heat shrink tubing hidden): State 1 (housing 101, first conductor 102, second conductor 103), State 2 (housing 201, first conductor 202, second conductor 203), and State 3 (housing 301, first conductor 302, second conductor 303), to show the different relative offset states between the second conductor and the first conductor.
